1. DESIGN AND EXPERIMENT OF A SAFFLOWER PICKING ROBOT BASED ON A PARALLEL MANIPULATOR
ABSTRACT To mitigate the large demand for safflower picking labour and the low efficiency of manual picking, a safflower picking robot that is based on a parallel manipulator is designed. The whole robot mainly consists of a walking device, parallel manipulator device, vision device, picking device, filament collection device, control system, and motor drive

2. Structure Comparison and Optimal Design of 6-RUS Parallel Manipulator Based on Kinematic and Dynamic Performances
Abstract The effects of distinctive parameters such as revolute joint angle or spherical joint location of mobile platform in a 6-DOF 6-RUS parallel manipulators on workspace, kinematic, and dynamic indices are investigated in this study to select proper structure commensurate with performance. Intelligent multi-objective optimization method is used to desig

3. Modelagem dos movimentos funcionais robótico-assistidos para a reabilitação dos membros superiores: redução dos graus de liberdade de um manipulador antropomórfico / Functional Movement Modeling for robot-assisted upper
A reabilitação robótica é uma ciência que permite o desenvolvimento de dispositivos ativos para vários processos no campo da saúde. No caso da reabilitação, substitui a assistência física por um dispositivo robótico, sob a supervisão do terapeuta. Segundo alguns autores, há muitas evidências de que os movimentos repetitivos podem ajudar na rea

5. Hyper-redundant robots with modules of parallel arquitecture. / Robô hiper-redundante com módulos de arquitetura paralela.
This research studies hyper-redundant robots focusing on the kinematics analysis. A hyper-redundant robot was developed based on modules of parallel architecture and binary actuators. Each module has three degrees-of-freedom, two rotational degrees of freedom with perpendicular axis and one translational degree of freedom. After searching for parallel struct

6. Uma contribuição ao desenvolvimento de manipuladores antropomorficos com enfase na utilização de musculos artificiais / A contribution to the development of anthropomorphic manipulators with emphasis in the use of artificial muscles
Este trabalho visou o estudo de manipuladores à semelhança do membro superior humano. Após o estudo do membro superior humano e dos robôs antropomórficos disponíveis tanto na industria quanto no meio acadêmico, utilizaram-se teorias de modelagem geométrica, cinemática direta e cinemática inversa para realizar o modelo de um manipulador robótico an

7. Contribuição ao planejamento de trajetória de robôs através de elementos de dinâmica, controle e otimização / Contribution to robot path planning through dynamics, control and optimization
Robotic manipulators are programmable devices designed to execute a great variety of tasks in a repetitive way. In industrial environments, the reduction of dynamic requirements associated to a specific task can result in productivity increase and cost reduction regarding the robotic operation and maintenance. Moreover, the reduction of such requirements can

9. Virtual kinematic chains to solve the underwater vehicle-manipulator systems redundancy
This paper addresses the kinematics of the Underwater Vehicle-Manipulator Systems (UVMSs). Due the adittional degrees of freedom (dofs) provided by the vehicle, such systems are kinematically redundant, i.e. they possess more dofs than those required to execute a given task, and need to be solved using some redundancy technique. We present an approach based

10. Modelagem e otimização de um robô de arquitetura paralela para aplicações industriais. / Modeling and optimization of a parallel architecture robot for industrial applications.
This work is about the study of parallel architecture robots, focusing in modeling and optimization. No physical prototypes were built, although the virtual models can help those willing to do so. After searching for an application that could benefit from the use of a parallel robot, another search was made, this time for the right architecture type. After s

12. Proposal of methodology for the modeling and control of manipulators
Industrial applications demand that robots operate in agreement with the position and orientation of their end effector. It is necessary to solve the kinematics inverse problem. This allows the displacement of the joints of the manipulator to be determined, to accomplish a given objective. Complete studies of dynamical control of joint robotics are also nece
